The United Nations Food and Agricultural Organization (FAO) has published a report on food fraud in fisheries, providing an overview of the state of affairs in a particularly vulnerable sector.
According to the document, written by Alan Reilly, former Chief Executive Officer of the Food Safety Authority of Ireland, the scale of the problem is a cause for international concern, with mislabelling and species substitution presenting the biggest challenge.
It establishes what the current situation is by citing a number of investigations and pieces of research, including a recent study carried out by Italian authorities that found 22.5 per cent of fishery products were mislablled, with the highest incidence recorded among cephalopods (like squid and octopus) and Asian imports.
Mr Reilly moves on to describe how food fraud impacts public health. He said: Public health is endangered when fish species that are toxic are substituted for non-toxic species. Public health is also put at risk when farmed species from polluted watercourses are substituted for marine fish.
He used a case study of 17 deaths caused by toxic puffer fish in 2008.
The report presents DNA barcoding as a promising tool against food fraud. It said: With the advent of molecular identification methods, such as DNA barcoding and next-generation sequencing, the possibility exists for far greater transparency in the fish marketing
chain.
Fish traceability is key to combating fish fraud, enforcing food safety regulations and ensuring high standards of sustainable fisheries management. Traceability is also critical for ensuring the quality of fish products and minimising health risks for consumers.
It concludes: The number of reports and reviews published in both the scientific literature and the popular media in the past decade provide adequate documentary evidence that fish fraud through mislabelling and species substitution is a widespread problem in both national and international markets for fish and fishery products.
While the scale of the problem has been investigated and reported in developed countries, much less is known about fish fraud in developing countries. There is a major expansion of e-commerce and online food sales, which present major opportunities for fraudulent trade in fish. In order to combat fish fraud, improved traceability systems are required that can reliably track fish from the point of harvest to the consumer’s plate.
Current traceability systems rely on a paper trail that documents such data as the geographical origin, species, and registration details of vessels. Experience from previous food fraud incidents, such as the European horsemeat scandal, shows that such documentation can be falsified.
